Determining the True Width of a Div

I am working with a div that has a class of 

myid_templates_editor_canvas-selection
.

<div class="myid_templates_editor_canvas-selection" style="position: absolute; font-size: 0px; left: 0px; top: 0px; width: 377px; height: 174px;"></div>

The width of the div is set to 377px, however, when I try to retrieve the width using the code 

alert($(".myid_templates_editor_canvas-selection").width());
, it returns 379px. Why is this happening? I need to get the exact width of 377px. Which function should I use to achieve this?

Answer №1

The reason is that the div contains a 1px padding/border, as mentioned earlier in the comments. To address this issue, consider using the following code snippet: 

alert($(".myid_templates_editor_canvas-selection").innerWidth());

Answer №2

Check this out

let canvasWidth = document.querySelector('.myid_templates_editor_canvasselection').offsetWidth;

window.alert(canvasWidth);
